Description

Automatic wall plastering machine

Technical Field

The invention relates to the field of construction machinery, in particular to an automatic wall plastering machine.

Background

Under the rapid development of society, the population is rapidly increased, more and more people gather in cities, the urbanization construction is accelerated, the living housing conditions of people are better and better, and meanwhile, more housings are needed to meet the living needs of people, so the house construction of the people is developed more and more rapidly. After a housing blank is built, mortar needs to be applied to the wall surface, which is a heavy task, and manual painting is generally adopted at present, so that the following problems are faced:

1) the painting engineering quantity is large, the manpower and material resources are required to be large, and meanwhile, the painting quality is also deficient to a certain extent;

2) the lower part of the wall surface can be directly painted by manpower, but the higher part is not easy to be painted, a frame is required to be built by the worker, painting is carried out on the frame, so that too much manpower is wasted, and the painting efficiency is lower;

3) because the work is carried out at a high place, the personal safety of workers has certain hidden danger when the workers work for a long time.

Based on the reasons, some automatic wall plastering machines have appeared in the prior art to realize automatic wall plastering and improve the wall plastering efficiency, but the automatic wall plastering machine has certain defects, if automatic feeding cannot be realized, manual feeding is needed, the labor intensity of workers is still very high, the feeding difficulty is increased when a higher position is plastered on a wall surface, the verticality and the positioning between the wall plastering machine and the wall surface are measured manually, and the positioning is inaccurate, the flatness of the plastered wall surface is low, and the like.

In foreign countries, the wall plastering and painting are mostly finished by spraying mortar, but the design and the use of an automatic wall plastering machine are not common.

For example: the korean Hasco company developed and produced an electric high pressure airless sprayer PRO-60N, which is composed of a main unit, a high pressure pipe, a nozzle, etc., and is suitable for spraying the outer side of large equipment and the wall of large buildings, and is not limited by places, but has disadvantages that its spraying material has certain requirements, and can only spray medium and high viscosity rubber, latex paint, etc.

The nose was actually germany as a wall finishing machine, and in 1958, german invented the first spray coater. To date, germany companies have been working on developing automatic wall plastering apparatuses, the most representative of which is WAGNER, and among the products, PC830 spraying machine, which is an electric airless spraying machine, has light weight, can pass particles of 3mm at most, has strong practicability, and is mainly used for plastering of building exterior wall adhesives.

In addition, the united states is the largest industry-intensive country in the world. The industrialization of the automatic wall plastering machine promotes the rapid development of the building industry, so that the automatic wall plastering machine is rapidly developed, for example, a spraying machine GPX220 is a model in wall plastering equipment, and the automatic wall plastering machine has the remarkable characteristics: convenient movement, large spraying flow, enough power, long service life and the like; the application range is wide, and the paint is suitable for spraying various materials.

In conclusion, the foreign wall plastering machine is developed earlier and has a perfect technology, but the foreign wall plastering machine is favored to spray and is less involved in an automatic wall plastering machine.
